10 Claims.

This invention relates to dispensers for powdered dentifrice and has for its object to provide a comparatively simple and inexpensive device of this character which is compact in con- 5 struction so that it may be conveniently carried4 A furtherobject is to provide one end of the handle with a sliding plate which forms a closure for the compartment, said plate being formed with a discharge opening adapted to register 20 with a controlling valve mounted in the dentifrice compartment for regulatingthe discharge of the dentifrice.

A' further object is to provide a-novel form of controlling valve which coacts with the slidg5 ing plate or closure to automatically lock the plate in open position.

A still further object of the inventionv is generally toimprove this class of devices so as to increase their utility, durability and eiliciency.

ent invention comprises a handle 5 4formed of I gutta-percha or other suitable material, one end of which is transverselyl enlarged at 6, while the other end thereof is tapered and terminates in a conical stud 1, the end of which is threaded, 5 as indicated at 8. 'I'he handle 5' is provided with a transverse partition 9 forming independent compartments I and II, one of which is adapted to receive dentifrice, preferably in powdered'form, while the other serves to re- 10 ceive and house a detachable4 brush head, indicated a`t I2. 'I'he brush head vI2 may be provided with any-style of bristles and the shank .thereof is formed with a conical socket I3 adapted to fit over the stud 1, there being l threads I4' formed in the small end of the socket I3 for engagement with the threads 8 whereby the brush head may be quickly and conveniently attached Ato or removed from the handlerl If desired, the shank of the brushA head may lbestrengthened by an annular reinforcing The dentifrice compartment I0 preferably extends approximately the entire length of the handle,l while the compartment II is formed with longitudinal slots IG-to permit free circulation of air therethrough and thus keep the bristles of the brush head in a dry, sanitary condition. 'I'he end of theenlargement 6 of the handle is preferablyarcuate in shape and the sidewalls thereof are formed with guiding grooves I1 in which is slidably mounted a correspondingly arcuate' closure plate I8. The closure plate I8 is provided withv a depending arcuate ange I9 and a terminal depending stop flange 20, which latter bears against theadjacent wall of the handle when the plate I8 is in closedvposition, asbest shown in Figure `1 of the drawing. The closure platey I8 is formed with a lateral nipple 2|. having an opening formed therein and adapted to register with 40;

the compartment I0 to permit the discharge of dentifrice on the brush head when'desired.

.As a means for controlling the discharge of provided a` spring actuated sliding valve 22 including a relatively short. cut-oi! plate 2l having'an opening 24 formed therein and adapted to register with the nipple 2l, said cut-offpiste being provided with a depending portion 2l to 50 terposed between the depending portion 25 and a centering lug 29 on thev wall of the compart ment I0 for the purpose of normally holding the valve in closed position. The valve stem 26 is provided with an annular groove 30 which is disposed in the path of the flange VI9 when the valve stem is pressed inwardly and permits free sliding movement of said plate while, at the same time, holding said valve stem retracted, there being -a notch or opening 3| formed in the flange I9 and adapted to receive a lcylindrical part 32 of .the valve stern when the stem is released s'o as to lock the plate in open position and permit movement of the valve stem therethrough. It will here be noted that when the valve stem is pressed inwardly to cause the opening 24 in the cut-off plate to register with the nipple ZI and permit discharge of the dentifrice, the closure plate is free to slide within the` grooves I1 and the closing movement of the plate I8 will cause the flange I9 to lock the valve stem in open position so that the outerend of the stem will not project beyond the side walls of the handle and form a surface projection.

Normally, the parts are in the position shown in Figure 1 of the drawing, that -is to say, with the brush head removed from the stud 'I and housed within the compartment II and with the` compartment I0 filled with powdered dentifrice, andin which position the device may be conveniently carried" in a pocket or in a purse or` hand bag. When it is desired to use the tooth brush, the plate is moved laterally by exerting av slight pressure on the nipple 2| until the adjacent end of the plate clears the compartment II and in which position the spring 28 will force the valve stem outwardly andv cause the cy' lindrical portion 32 thereof to enter the notch 3l and thus lock the plate agaiinst further movement and at the same time prevent discharge of the dentifrice from the compartment I0. The brush head I2 is then removed from the compartment II and the handle positioned over the bristles of the brush head after which the valve stem is pressed inwardly which causes the opening in the cut-off plate to register with the nipple and thus allow a predetermined quantity of dentifrice to be deposited on the bristles of the brush head. Ihe lbrush 7head4 is then screwed onto the stud I and the brush used in the usual manner for cleaning the teeth. After the teeth have been'cleaned, the brush head is detached from the stud 1 and inserted in the compartment II. By th'en pressing inwardly on the valve stem 26, the cylindrical portion 32 of the valve stem will' clear the notch 3I and cause the groove` 30 to register with the flange I9 of the sliding plate and in which position the plate may be readily moved laterally of the handle so as to form a closure for both of the compartments of the handle.

It will thus be seen that there is provided a comparatively simple and inexpensive device by means of which a toothbrush and a quantity of dentifrice may be compactly housed in a unitary structure so as to be conveniently carried-in a pocket or hand bag and ready for immediate use and embellished or ornamented in any suitable manner to impart a pleasingornamental appearance thereto. It will also be understood that while it is preferred to make the handle of hard rubber, said handle and brushhead may be made ofI celluloid, bakelite, metal, or any other suitable material having the desired strength without departing from the spirit of the invention.
